BAND SPOUT OR TRUMPET.

SPECIFICATION fOrmiIlg part of Letters Patent NO. 789,121, dated. May 2, 1905.

Original application filed June 14, 1902, Serial No. 111,721. Divided and this application filed May 28, 1904. Serial No. 210,306.

To all whom it may concern:

Be it known that I, WILLIAM DOUGLASS, a citizen of the United States, residing at Phillipsburg, in the county of Phillips and State of Kansas, have invented certain new and useful Improvements in Band Spouts or Trumpets, of which the following is aspecification, reference being had therein to the accompanying drawings.

The present invention relates to deliveryspouts for handling a band of compressed fibrous material, and is designed primarily for usein self-binder harvesters of the type shown in my application for patent filed June 14., 1902, Serial No. 111,721, of which application the present case is a division.

WVhile the band-spout herein shown and described is, as stated, designed particularly for use in connection with the harvester disclosed in the aforesaid application, it will be understood that 1 do not limit its use to any particular type of harvester, or, in fact, to any particular type of machine, as it will be obvious that the spout may be used wherever it is desired to deliver a band of fibrous material, such as straw bands, in shaped and compressed condition.

Briefly stated, the spout which I have invented,and which will be described hereinafter in detail, comprises a plurality of movable sections so arranged relative to each other that while normally the delivery-opening of the spout is held at its minimum diameter, yet the movable sections may yield relative to one another, so that the delivery-opening of the spout will increase in diameter and accommodate itself to variations in the diameter of the band as it passes from the spout.

In order that my invention may be better understood by those skilled in the art, I have illustrated in the accompanying drawings one embodiment of my invention, and in said drawings Figure 1 is a view in end elevation of the spout looking into the delivery end thereof. Fig. 2 is aview similar to Fig. 1 looking into the receiving end of the spout. Fig. 3 is a top plan view. Fig. 4 is a cross-sectional view on line 5 5 of Fig. 3.

Referring to the drawings by letters, like letters indicating like parts in the several views, g indicates one member of the spout, which in the present case is provided with a standard 9, by which it may be secured in proper position in or upon the harvester or machine in which the spout is used. The said spout member g is substantially U-shaped in cross-section and of conical form longitudi' nally, its sides being extended somewhat at the rear of the spout and provided with pivotlugs g. Secured to said pivot-lugs by means of suitable pivot-pins g so as to swing freely thereon, is the second member g of the spout, which member is approximately of the same shape as the other spout member, but smaller than the first-named member g, so that the said pivoted member 9 can move freely within the stationary U-shaped member 9 ofthe spout. The said movable member g is normally held in the position shown in Figs. 1 and 3 by means of a spring g secured to one of the pivot-pins g and bearing at its free end against a lug or projection 9 upon the movable member g, said lug g serving also as a stop to limit the inward movement of the movable member g by striking against the edge of one of the limbs of the stationary U-shaped section g, as clearly shown in Fig. 3.

It will be seen that the spout constructed as above described will readily yield to accommodate variations in the size of the band passing therethrough, the movable member gt swinging on its pivots against the spring g so as to open the delivery end of the spout more or less. It will be observed, however, that while the spout is capable of expansion there is no interruption of the smooth interior surface of the spout, for the closelyfitting U-shaped members preserve at all times a smooth interior surface for the band to travel over, thus avoiding any danger of the loose strands of straw or other material becoming caught and entangled in the spout and causing breaking or interruption of the moving band. This feature of my invention 1 consider of great importance, for the reason that it is essential to the effective operation of spouts of this character that entanglement of the band fibers or strands with the spoutsurface be guarded against, and this I have done in a simple and effective manner by the construction described.

From the foregoing it will be seen that I have provided a band-delivering spout of simple construction, and one which will readily accommodate itself to variations in the diameter of the bands passing therethrough without danger of catching or entangling the straw or fiber of which the band may be composed with the inner surface of the spout. While I have described a particular construction of.

spout, and thatthe best now known to me, I do not wish to be understood as limiting myself to any of the details shown and described, except so far as I am limited by the terms of the appended claims,as the construction shown is capable of modifications and changes within the skill of the mechanic, and all such changes I deem within the range of my invention.

Having thus described myinvention, I claim and desire to secure by Letters Patent 1. A cone-shaped band compressing and delivery spout composed of a plurality of movable members.

2. A cone -shaped compressing deliveryspout composed of a plurality of members pivotally connected with each other.

3. A band-delivery spout composed of a plurality of members pivotally connected with each other, and means for holding said members normally in closed position.

4:. A band-delivery spout composed of a plurality of members pivotally connected with each other, and a spring for holding said members normally in closed position.

5. A cone-shaped band-delivery spout composed of two members pivoted together at their rear ends.

6. A cone-shaped band-delivery spout composed of two members pivoted together at their rear ends, and a spring to maintain said members in closed position.

7. A cone-shaped band-delivery spout composed of two members substantially U-shaped in cross-section, pivoted together at their rear ends, and a spring to hold said members in closed position.

8. A cone-shaped band-delivery spout composed of two members substantially U-shaped in cross-section, pivoted together at their rear ends and sliding one within the other, whereby the spout will accommodate various sizes ofbands and at the same time present a smooth interior surface.

9. A cone-shaped band-delivery spout composed of two members substantially U-shaped in cross-section, pivoted together at their rear ends, a spring to hold said members in closed position, and a stop to limit the movement of said members toward each other, whereby the spout will accommodate various sizes of bands and at the same time present asmooth interior surface.

In testimony-whereof I affix my signature in presence of two witnesses.

WILLIAM DOUGLASS.
